Attempting to placate the side I currently oppose, I'd offer the compromise of turning one of the tanks into a hard mode tank. We can have it require stance swapping to perform its primary function, effectively require a lot more button presses and ability management to deal its damage and mitigate. Kind of like a "hard to learn, really hard to master" type of tank.
Here's the caveat -- at maximum performance, it's no different from its contemporaries. Similar mitigation, utility and damage potential. It's not guaranteed a raid spot, and still has to compete with "simple is best" demagogues like me. Assuming this is truly about the gameplay ("tank gameplay is so boring") instead of questionable pursuits [?], we'd all get what we want, right? Those like me get to play like tanks, and those of the other side can press all their buttons and swap all the stances, with both sides generating similar results so that no one gets kicked to the curb.
